Silicon Bronze Tig/solder Description

Silicon Bronze TIG / Solder  Uses For 

1. What It Is:
Silicon bronze is an alloy mainly composed of copper (Cu) with about 3–5% silicon (Si) and small amounts of manganese, tin, or zinc.
When used in TIG (Tungsten Inert Gas) welding or as brazing/soldering filler, it is commonly called silicon bronze TIG wire (AWS classification ERCuSi-A).

2. Properties

• Melting temperature: ~950°C (lower than steel, higher than silver solder).

• Excellent corrosion resistance (especially to salt water and chemicals).

• Good strength and ductility (doesn’t crack easily).

• Smooth, clean weld appearance—golden bronze color.

• Low heat input compared to steel welding, reducing distortion.

3. Common Uses

4. Key Advantage

Silicon bronze TIG is not a fusion weld on steel—it’s technically a braze, meaning the filler melts but the base metal doesn’t. This allows joining dissimilar or thin metals with minimal warping.
